Pregnancy and breastfeeding is such a special time. New beginnings, new life, new family. A lovingly decorated nursery, new onesies and hand-knitted blankets. But it’s what’s happening on the inside that is most important.
The nutrients a woman provides to her baby during the period of pregnancy and breastfeeding, affects their growth and development and can have lasting implications on their long-term health. Certain nutrients are especially important to fuel healthy development.
“Choline is often referred to as the unknown essential nutrient as few people, even health professionals, know about it” says choline researcher Professor Marie Caudill.
“Dietary recommendations for choline were not established until 1998 as compared to the early 1940s for the other nutrients. In addition, only recently has choline been featured in nutrition textbooks and included in the curriculum for nutrition majors.”
Choline is one of the few nutrients, which actually becomes more important during breastfeeding. The recommended adequate intake increases from 440mg during pregnancy to 550mg during breastfeeding.  Yet 90 – 95% of pregnant women aren’t meeting recommended levels 
“Our preliminary dietary studies clearly show an insufficient choline intake compared to the recommended levels,” said Curtis, an analytical chemist and project leader for ongoing choline research at the University of Alberta 
During pregnancy, choline works alongside folate in the development of the neural tube, as well as supporting healthy brain development which has been shown to have lasting effects on learning and memory function.
“The demand for choline during human pregnancy is high because large amounts are required for cell division and tissue expansion. Recent findings from my laboratory suggest that supplementing the maternal diet with extra choline (i.e, 550 mg choline/d) may improve maternal and child health outcomes by enhancing placenta function easing babies response to stress.”
“We recently showed that a higher maternal choline intake attenuated the production of a protein that contributes to preeclampsia. Thus, mothers not consuming enough choline during pregnancy may be at greater risk of placental dysfunction” says Professor Caudill.
“Choline is needed for cellular division, tissue expansion, lipoprotein synthesis and one-carbon metabolism; all of which are accelerated in pregnancy. In addition, large amounts of choline are present in human milk thereby increasing the choline requirement among lactating women.”
The importance of choline is summed up well by Gerald Weissmann MD Editor in chief FASEB Journal:
“The importance of choline cannot be overstated as we continue to unravel the role it plays in human health and development”
Animal products are richest food sources of choline including egg yolks, red med, chicken and fish. Vegetarians and vegans are at most risk of choline deficiency.
Other good sources of choline include lecithin granules, baked beans, kidney beans, lentils, brussel sprouts, broccoli, spinach, cauliflower, wheatgerm and oats.
Due to the importance of choline in pregnancy and breastfeeding, the American Medical Association recently made recommendations to include choline in all prenatal supplements. 
Currently in Australia, most prenatal supplements don’t provide this important prenatal nutrient. I recommend women choose a prenatal supplement which provides 300mg of choline alongside a healthy variety of choline-rich foods.
